UV-5151 is a liquid blend of a hydrophilic 2-(2-hydroxyphenyl)-benzotriazole UV absorber (UVA) and a basic hindered amine light stabilizer(HALS).It has been designed to fulfil high cost/performance and durability requirements of exterior waterborne and solvent borne industrial and decorative coatings. The broad UV absorbance of the used UVA makes it suitable for a wide range of coatings for wood, plastics and metal. The synergistic combination imparts superior coating protection against gloss reduction, cracking, blistering, delamination and color change and provides full substrate protection. Appearance : Viscous amber liquid. Active ingredient, %: 93min. Viscosity at 25 degree: 7000mPa.s max. Density at 20 degree: 1.10 g/cm3 Ash, %: 0.1max. Transmittance: 460nm 95%min. 500nm 97%min. UV-5151 is a universal light stabilizer which can be used in a variety of solvent borne and waterborne industrial and decorative coating systems
